To alt-whom w 1,-tcg c0ac0rn Be it;- known that L Amine; Looiaus' citizen of the Unit-ed States, and resider Detroit l i ayne county, State of Michi have in-venterlcertain new and useful prorenients in h-hator-Veliivl-w following is a specification.

This invention relates to motor of which me.

and particularly' to the running gear constriict-ion'.

In most mot is connected to the frame by Springs, rel'ntire'to the frame, and in order to relieve these springs from the {hiring action oi? the tetl with the ice ronls.

or vehicles the driring arlc frame through tie rods or (L The forward pivotal point of M13549 tie rocls determines the arms around which the axle oscillates, and as one end of? the axle more urwvarclly relative to the frame fart than the other enil at a .,rtime, the rods are necessarily oscilla 0' somewhat about-itheir longitudinal axes, so that their and the frame should i In l joints with the axle of a universal character. the presentinvention, one of these distance rotls-is-illustral'ed .hovine' ball and socket l connection with both the axle and the frame, and as both of these joints alike, only one of them will he (lCS fiheil in detail.

One of the objects of this invention is to provide a tie rccl having double universal joint connect-ion in which the joints may be freely lubricated and protected from dust, I

and in which the wearing parts may be easily anchquiekly removed anti replaced Other ohjects will appear from the following description, taken in connection with the drawings, in which,

Figure 1 is a side eleration and part section, showing parts of a motor vehicle frame and axle, together with a distance l'Ofl connecting'theni; Fi i. 2 l; front elevation. of the forward end of the (list-unto rod and its bracket; 3 is a-sectionu'l view through one of the joints of the distance rod; Figs. 4, 5 and (l are detail views; and Fig. 7 is a view- \\'ith parts broken away .Qhowing two of the joint parts partly a n hlerl.

Referring to the drawings 10 represents one of the sicle bars of a motor vehicle frame. 11 is the'tnbular supporting; axle housing the a spring by which cl upon the axle means of which permits the axle to oscillate 1 may I er j . ward enrl of the mo '15 connected ton bracket 'ehicles cm the frame.

1.8, suspended The joints by which i the rod is; connected to pass these. l brackets will now be described in detail; 1 A j pin 19 is secured in the bracket 18., ashy nut t 520, amlou the projecting end of this pin is i a wearing member 21 in the form of the central zone of a sphere, this member being; I secured thereon hr :1 taper lit and by a nutilZ.

This wearing inc- 1 I i Fig. 4. and it pare .ahly keyed to the pin 1 if) to in-event rotation thereon. Surrounding the member 1 i ring 23, the interior central Dart of wh ch also in the form of the can so l a worinng member 21., anti in angler that .1 member 21 may be inserted into the ring 23, the latter is provided with opposed longitu ilinztl sloth 2%, as show-m particularly and, (l. inc s of slots-the member '21 may 1110 r enilwise into the center of l the ring 9?, a by their turningthe in in her 21 about lii, it is held ritii-n part 05' said ring. The ring 23 is surrouinlecl by the eye portion ing therein by a bolt 26. 1

From tl. hove, it will be seen that a hall 1 and socket joint is obtained, having" a very large wearing. surilace, and inwhich the wearing member 21 is easily and cheaply renewed. To make the replacement, it' is only not ssar to ren'iove the nut 22, slide the tie rod eon together with the wearing piece 21., oil oi the pin 19, and then. remove the, wearing piece 21 trend the ring 23, the latter operation requiring simply that the wvearingpiece i l. be turned on its axis until it registers with the slots 24, and then removed eiu'li-i ise. A. new wearing piece may hs easily be put in place.

For the purpose of protecting the joint from dust and dirt, and for retaining grease or other lubricant on the win-nin "surfaces of the joint. the ring 23 is oiil at its end adjacent the bracket l in he form of an angular lizmge 27. which enters a spher- -ical groove 98 in the bracket. Packing n au; i in A l l l l l l l l l l r 21 is shown in detail in that it has in? ry or? the in Figs. 5'

theend piece 16, and it is held against l'urn terial "'29 is placed in a groove in the pcriphery ot' the flange 27 to obtain a good joint between said flange and the wall of the groove 28. The other end of the ring 23 is threaded and provided'n'ith a cap 30 and a spring 31 may be arranged between the cap and a washer 32, which is secured in place by the nut 22, whereby all play in the joint 1., taken up tor the purpose of preventing rattle in the joint.

The joint may be packed in grease when it is assembled, or; it may be supplied with grease or other lubricant throughan opening in the ring a channel 34; in the shank of the end piece 16, and a grease cup 35 communicating with said channel.

It will be observed that the end of thedistance rod has a universal action at the joint, so that there are no twisting strains on the rod as the supporting axle is moved in arious directions relative to the frame, as by driving the vehicle over rough roads. It will also be noted that the joint is well protected from dirt and mud, and the lubricant supplied to it is retained therein.

Various modifications of the structure shown in the drawings may obviously be made without departing from the spirit and scope of the invention, and all such modifications are internled to be covered by the claims, j

Having thus described my invention, what I claim and desire to secure by Letters Patent, is, V

1. In a motor vehicle, the combination with a bracket, of a brace rod having an end piecetin the form of an eye, a ring within said eye and secured thereto, a. wearing;

member supported on the bracket and in contact with the rlng, a cap over the outer end of said ring, and means between the inner end of said ring and said brackctfor preventing the ingress of dirt to the joint,

2. A joint comprising an inner member in the form of the central zone of a sphere. and an Outer member in the form of a ring havinc; interior spherical surfaces to fit the inner member, said outer member being so formed that the inner member may be as sembled in the outer member by moving i t edgevvise to a central position in the ring, andthen turning it, as'on a pivot, to bring; the spherical surfaces in contact.

3. A joint comprising an inner member in the form of the central zone of a, sphere, an

outer member in the form of a ring adapted i to surround the inner member,.and having transverse slotsfithrough which the inner member may enter the ring, and a pin adapted to be secured to-the inner member cured to said bracket, of a ring surrounding sfihl wearing member, a brace rod surrounding and secured to said ring, and a spring arranged between said wearing member and said ring to take. up the wear-between said members. i

G. In a motor vehicle, the combination with a bracket, a pin supported thereby, and

a wearing member in the form of the central zone of a sphere secured to said'pin, of a ring surrounding said wearing member and having a packed joint in engagement with a s 'iherical surface onsaid ring, and a brace rod secured to Said ring.

"7. In a motor vehicle, thecombination with a bracket, a pin supported thereby, and a wearing member in the form of the central zone of a sphere secured to said pin, of a ring surrounding said wearing member and having" a packed joint in engagement with a spherical surface on said bracket, :1 cap over the outer end of said ring, a brace rod secured to said ring. and a compression spring between said wearing member and said cap. whereby the wear inthe joint is taken up.

The combination with a bracket and a brarc rod, of a joint between said bracket and brace rod comprising a spherical memher on the bracket and a ring on the brace rod, said brace rod and ring having channels lradiug to the wearing surfaces of the joint. and a grease cup on the brace rod in rod.
